During a series of experiments designed to study mineral metabolism on rice diets (Cullumbine, Basnayake, LeMottee & Wickramanayake, 1950), it was also found possible to estimate the nitrogen content of the food and excreta for the group of twelve subjects and so to determine whether there were any differences in the nitrogen metabolism of subjects when eating diets first high in unpolished ric...

Recent clinical studies have shown that acute exacerbations of chronic obstructive pulmonary disease (COPD) are characterised by disturbances in the balance between dietary intake and energy expenditure [1, 2] as well as by a negative nitrogen balance [3]. Since weight loss prior to and during hospitalisation for an acute exacerbation has been related to poor outcome in terms of mortality and r...

A study was carried out to investigate nitrogen metabolism in response to cecal ligation and colostomy in chickens. We used colostomized plus ceca-ligated chickens fed a low protein diet or a low protein diet supplemented with urea. When both types of diets were fed, nitrogen balance and utilization tended to increase by cecal ligation while total nitrogen excretion tended to decrease. Colostom...

ter digestibility, apparent digestible energy and apparent metabo-lizable energy are similar to the published values of Adeola and Bajjalieh (1997) and NRC (1998). Total nitrogen intake was similar (P > 0.10) between the corn varieties (Table 3). The amount of nitrogen digested (0.03 and 0.03 lb/d) and retained (0.01 and 0.01 lb/d) were similar (P > 0.10) between the corn rootworm protected and...

OBJECTIVE To assess whether a late evening meal would improve nitrogen balance in patients with cirrhosis of the liver. DESIGN Randomised crossover study of meal schedules comparing three meals a day with four or six meals a day, the four and six meal schedules both including a late evening meal (2300). SETTING Metabolic ward. PATIENTS Seven men and two women aged 34-66 with cirrhosis of ...

1. Solutions of the globulin fraction of alkaline extracts of the anterior lobe of beef pituitary glands, when administered intraperitoneally or subcutaneously to dogs for 1 or 2 days, greatly increase the nitrogen balance. Urine nitrogen falls markedly, and at the same time blood non-protein nitrogen decreases, while the nitrogen of the feces remains the same. 2. The nitrogen gained may either...

INTRODUCTION Hyperglycemia and protein loss are common in critically ill patients. Insulin can be used to lower blood glucose and inhibit proteolysis. The impact of moderate insulin therapy on protein metabolism in critically ill patients has not been evaluated. We compared urinary nitrogen excretion, nitrogen balance, serum albumin concentrations, prealbumin concentrations, and clinical outcom...

OBJECTIVE To evaluate protein intake, nitrogen balance and nutritional status of clinically stable patients with Parkinson's disease (PD). METHODS A cross-sectional study of PD patients Hoehn-Yahr scale stage 1-3 and subjects with no neurologic disease (controls) matched for age and gender. All participants underwent a diet history interview, anthropometric measurements, bioelectrical impedan...

the possibility of manufacturing and effects of a slow release non-protein nitrogen product on ruminant nutrition were evaluated in two separate experiments. in first experiment, making of slow release component was followed by connecting branched carbon chain to the molecule of urea to reduce the degree of solubility. then, the sample product was analyzed to assess its chemical structure, and ...

This study explored if a combined supplementation of GH and IGF-1 had an additive effect on whole body nitrogen economy, energy, substrate and skeletal muscle metabolism following surgical trauma. Patients were randomized to controls (C; n = 10), to GH (0.15 IU/kg/injection) (GH; n = 7) or GH combined with IGF-1 (40 mug/kg/injection) subcutaneously twice a day (GH-IGF-1; n = 9) together with st...
